Connor Stedman: Carbon Farming
Connor Stedman: Carbon Farming Sequestering atmospheric carbon through natural means Climate change remains a hotly debated topic. But a scientific fact not up for dispute is the pronounced spike in the concentration of carbon dioxide in the Earth’s atmosphere over the past two centuries. There’s a building urgency to find solutions that can manage/reverse that […]
Split personalities: We like some science, but not all of it
Split personalities: We like some science, but not all of it We modern folk are in a bind. We embrace what the sciences and the technology that flows from them have to offer, but we refuse to believe that we live in the world described by those very sciences. Here I’m not merely talking about […]
Did The EPA Just Go Rogue Again
Did The EPA Just Go Rogue Again In late January, days after Donald Trump became president, various government workers employed by the EPA “defied” the president with what at the time appeared to be rogue twitter accounts emerging from the environemntal agency, most notably the Badlands National Park which slammed Trump’s climate change proposal. “Today, […]
Toward a More Reflective Planet
Toward a More Reflective Planet CAMBRIDGE – The last time the atmosphere held as much carbon dioxide as it does today was about three million years ago – a time when sea levels were 10-30 meters higher than they are now. Climate models have long struggled to duplicate those large fluctuations in sea levels – […]
Top Obama Energy Official Says Administration Rejects “Keep It In The Ground” As Climate Strategy
Top Obama Energy Official Says Administration Rejects “Keep It In The Ground” As Climate Strategy “We’re certainly not advocating any strategy for reducing hydrocarbon emissions by keeping oil in the ground…that’s not a position.” This was the response of Christopher A. Smith when he was asked what he thought of the “growing movement of keeping oil […]
Shrimps sound ocean acidity alarm
Shrimps sound ocean acidity alarm The snapping shrimp is the noisiest marine creature in coastal ecosystems. Image: Tullio Ross/University of Adelaide The effect of the sea absorbing increased carbon dioxide in the air has damaging consequences for the noisy snapping shrimp and marine life in coastal rock pools. LONDON, 6 April, 2016 – The slow change in water […]
Can Geology Tell Us What is Warming the Climate?
Can Geology Tell Us What is Warming the Climate? On Monday this week, and rather late in the day, Dr Colin Summerhayes from the Scott Polar Institute, Cambridge University, left this lengthy comment at the end of the thread on Prof. Richard Lindzen’s post called Global Warming and the Irrelevance of Science. I wanted to respond to some of the […]
The problem with a carbon tax in Canada
The problem with a carbon tax in Canada Last week, Environment Minister Catherine McKenna indicated the federal government has not yet determined the national minimum carbon price which is part of its climate strategy. McKenna rejects any assertions the current economic environment is not the time to impose carbon pricing. Frédéric Bastiat (1850) forewarned of […]
Tomgram: Bill McKibben, It’s Not Just What Exxon Did, It’s What It’s Doing
Tomgram: Bill McKibben, It’s Not Just What Exxon Did, It’s What It’s Doing The time scale should stagger you. Just imagine for a moment that what we humans do on this planet will last at least 10,000 more years, and no, I’m not talking about those statues on Easter Island or the pyramids or the […]
More warming will bring a more polluted future
More warming will bring a more polluted future Global warming wil increase airborne aerosols and cause more atmospheric pollution, scientists say. LONDON, 15 November, 2015 – The future is slightly obscured. The outlook is less than clear. For once, such phrases are not metaphorical. A world of global warming could mean a growing haze of solid and […]
As CO2 Levels Rise, Obama Still All Talk And No Action
As CO2 Levels Rise, Obama Still All Talk And No Action President Obama is once again talking out of both sides of his mouth with regard to the need to protect the environment. After joining Facebook last week, the President used his very first video post to address the issue of climate change. The President said in the […]
2% Solutions for the Planet
2% Solutions for the Planet Since we live in an era of big problems, we tend to spend our time thinking of big solutions. Thinking big, however, can have a paralyzing effect on taking action. In my new book Two Percent Solutions for the Planet, I take readers on a journey around the world where low-cost, easy-to-implement solutions are regenerating the […]
Exxon’s Own Research Confirmed the Role of Fossil Fuels in Global Warming Decades Ago
Exxon’s Own Research Confirmed the Role of Fossil Fuels in Global Warming Decades Ago Minale Tattersfield / CC BY 2.0 Oil giant Exxon conducted cutting-edge climate research in the 1970s, and then, without disclosing the findings of its scientists, worked to manufacture doubt about the scientific consensus of its own research. A groundbreaking investigation shows how the […]
Nonlinear: New York, London, Shanghai underwater in 50 years?
Nonlinear: New York, London, Shanghai underwater in 50 years? Those under the impression that climate change is advancing at a constant and predictable rate don’t understand the true dynamics of the issue. The rate of increase of the carbon dioxide concentration in the atmosphere, the main driver of climate change, went from 0.75 parts per million […]
We May Have Already Committed Ourselves to 6-Meter Sea-Level Rise
We May Have Already Committed Ourselves to 6-Meter Sea-Level Rise Even if humanity were to stop throwing carbon dioxide and methane into the atmosphere today, a catastrophic rise in sea levels of six meters may be inevitable. Two previous prehistoric interglacial periods, in which the carbon dioxide content of the atmosphere was believed to be […]
